Duramboros

Duramboros

Giant brute wyverns with hammer-like growth on their tails. They subsist on fallen or withered trees, often using their tails to knock said trees over. Researchers speculate that the lumps on their backs act as some sort of energy source.

Once you complete the The Moving Mountain 8 Star Quest a High-Rank Duramboros will occasionally be found in Moga Woods at night.
